In Dynamic susceptibility contrast MR imaging (DSC-MRI, or simply DSC), Gadolinium contrast agent (Gd) is injected (usually intravenously) and a time series of fast T2*-weighted images is acquired. As Gadolinium passes through the tissues, it induces a reduction of T2* in the nearby water protons; the corresponding decrease in signal intensity ...
Dynamic susceptibility contrast: DSC: Measures changes over time in susceptibility-induced signal loss due to gadolinium contrast injection. [20] Provides measurements of blood flow; In cerebral infarction, the infarcted core and the penumbra have decreased perfusion and delayed contrast arrival (pictured).

There are different techniques of Perfusion MRI, the most common being dynamic contrast-enhanced (DCE), dynamic susceptibility contrast imaging (DSC), and arterial spin labelling (ASL). [11] In DSC, Gadolinium contrast agent (Gd) is injected (usually intravenously) and a time series of fast T2*-weighted images is acquired. As Gadolinium passes ...

Susceptibility-weighted imaging (SWI) is a new type of contrast in MRI different from spin density, T 1, or T 2 imaging. This method exploits the susceptibility differences between tissues and uses a fully velocity-compensated, three-dimensional, RF-spoiled, high-resolution, 3D-gradient echo scan.
WASHINGTON (Reuters) -U.S. unit labor costs grew far less than initially thought in the third quarter, pointing to a still favorable inflation outlook even though price increases have not ...
The Knicks are the only team with the potential to play three games this week, which gives McBride an edge in counting stats over most of the available waiver pool in points or category leagues.
The NFL playoffs are nearly in sight and the heat is on for some teams still in the fight to make the postseason.. Week 15 saw the number of teams that have qualified for the playoffs increase to ...
